Threonine

An essential amino acid for immunity and collagen formation.

Definition

An essential amino acid supporting immune function, collagen synthesis, and serves as a precursor for glycine in the body.

How it works

Threonine is an essential amino acid with a hydroxyl side chain that gives it unique chemical properties, allowing it to serve as a precursor for glycine (the most abundant amino acid in collagen). This makes threonine particularly important for connective tissue health, joint integrity, and collagen formation throughout the body. Threonine plays significant roles in immune function by supporting antibody production and immune cell development. The amino acid is also involved in fat metabolism and central nervous system function. Unlike some amino acids, threonine cannot be synthesized from other compounds, making dietary intake essential.

Role

Supports collagen and connective tissue formation, enhances immune function, and aids fat metabolism.

Examples

  • Pork
  • Beef
  • Chicken
  • Fish
  • Eggs
  • Soy
  • Cottage cheese
  • Nuts
  • Seeds
  • Legumes

Recommendations

Ensure adequate threonine intake through varied protein sources to support joint health and immunity. Particularly important for athletes and individuals with connective tissue concerns.

Key takeaway

Threonine is essential for collagen health, immune function, and cannot be produced by your body.
